What happens to capacitor’s charge when the plates are moved further apart? In my physics textbook there is an example of using capacitor switches in computer keyboard: Pressing the key pushes two capacitor plates closer together, increasing their capacitance.
I understand that when the separation between the plates of a charged capacitor is increased, the voltage increases. But I'd really like to know what happens to the plates if the capacitor is fully charged , disconnected from the charging circuit and then the plates are moved apart from each other by an infinite distance.
Q. A parallel plate capacitor is charged and the charging battery is then disconnected. If the plates of the capacitor are now moved apart by means of insulting handles : Q. A parallel plate capacitor is charged to a definite potential and the charging battery is disconnected. Now if the plates of capacitor are moved apart, then:
What happens when plates of a fully charged capacitor are isolated from each other? I'm a mechanical engineering student and I'm working on a project that involves a high voltage capacitor. I understand that when the separation between the plates of a charged capacitor is increased, the voltage increases.
Let us imagine that we have a capacitor in which the plates are horizontal; the lower plate is fixed, while the upper plate is suspended above it from a spring of force constant k k. We connect a battery across the plates, so the plates will attract each other.
Charge on plate remains q as charging battery is removed. The charge on the capacitor remains constant. Capacitance decreases as the plates of capacitor are moved farther apart. The options (a) and (c) are incorrect. Hence V increases. Option (b) is correct. ∴ U increases. Option (d) is correct. Q.
As the plates were pulled apart, the voltage went up. This comes from the elemental formula Q=CV. Pulling the plates apart lowers the capacitance. The charge didn''t go …
A parallel plate capacitor is charged an then disconnected from the charging battery. If the plates are now moved farther apart by pulling at them by means of insulating handles, then Q.
There is a force (F) between the plates. Now we gradually pull the plates apart (but the separation remains small enough that it is still small compared with the linear dimensions of the plates and we can maintain our approximation of a …

In the parallel-plate capacitor of Fig. 24.2, suppose the Plates are pulled apart so that the separation d is much larger than the size of the plates. (a) Is it still accurate to say that the …
If you gradually increase the distance between the plates of a capacitor (although always keeping it sufficiently small so that the field is uniform) does the intensity of the field change or does it …

The problem asks you to calculate the magnetic field generated as two parallel capacitor plates are pulled apart. Let the plates be circular with radius R. The plates have separation d at time t …
The two plates of a capacitor are charged by a battery. The plates are then disconnected from the battery and pulled apart so that their separation is doubled. Explain how each of the following …
The bottom line is: the work done pulling the plates apart, plus the energy lost thereby from the capacitor, both go into recharging the battery—no energy has disappeared. Dielectrics
